Here are a couple tips to keep from getting locked out, as facebook is currently blocking many new accounts.

• Recycle old accounts - this is the best option, if possible.
• Set your character name in Hangul or Chinese; but remember to put english in your alternate name so people can find you easier.
• If choosing to use the english idol name, use the weird letters and symbols so facebook doesn't recognize it.
• Set your privacy settings to 'friends of friends' or 'friends' only.
• In your privacy settings, set a security question (if given the option) and provide an answer.
• Enable secure browsing.
• Don't use the idol's real hometown, high school, etc; facebook can track similar accounts so it would be best to use random places and names.
• If all else fails, make a new account under a different name and change it after.
